AFR for Nitorus
OK you nitrous shooters. I've finally got my data logging system going on my bike. I've read and been told several different AFRs to run between 11.2 and 12.8 on the gas. I'm looking for as much info as I can get since I'll have real time track data to work with. Thx in advance.

Here's my dyno A/F (12.5 to 12.8) info with a Muzzy 45rwhp shot on C12. We beat on it for 3 hrs at Champion Cycle in 85 degree weather to get the right power/motor safe combo. Blue line is the juice mixture........Hope it helps.

Video of the final 242hp n2o dyno run.......Listen to this baby wind up thru 11,000 rpm, you can't even hear the n2o come in - note the juice comes off at 10,500 hence the residual 13 to 1 A/F as the fuel goes away faster then the spray in the air-box - all safely controlled by the C12.

Called Sabin Performance and got it straight from the horses mouth. 12 - 12.5 is where he tunes to. That's the area I was thinking too. Thx for the input cliff.

Best of success Bruce, with the right fuel (detonation is the killer) this motor loves spray.....Note from the dyno print out, we did 19 runs on the motor and 14 more on the juice, as we fine tuned the mixture for seemless performance, all in 4+hrs......What a bike!
Cheers,
Cliff
